“[M]ay not literature (and, in particular, fiction) be considered a desperate and permanently thwarted effort to produce a unique form of expression? Something like a cry, perhaps, a cry that, somehow, inexplicably contains all the millions of words that have ever existed, anywhere, in any age. In contrast with the spoken word and its classifying function, the purpose of writing seems, rather, to be a quest for the egg, the seed, nothing more.”
